CF VICTORIA PARK, XV'ESTERN ROTARY MIXING DEVICE.

Application filed September 27, 1924. Serial No. 740,214.

To (1Z6 whom it may concern.

Be it known that HENRY GORDON CAMP- BELL, of 229 lVilliam Street, Perth, in the State of lVestern Australia, Commonwealth ofAustra-lia. has invented an Improvement in Rotary Mixing Devices, of which the-following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to a rotary mixing device.

The invention particularly relates to a rotary mixing device for an internal combustion engine in which it is inserted between the carburetor and the engine manifold. 7 It is well known that the conventional means for charging air with vapour to obtain a mixture to be subsequently exploded in the cylinder is comparatively inetiicient in that the atomization is imperfect;

The present invention consists broadly in interposing between the carburetor and the engine manifold a member or members rotatable by the engine suction, whereby atomization is improved and the mixture becomes substantially uniform in composition.

To enable the invention to be more readily understood reference will now be made to the accompanying drawings, in which Fig. '1 is a side elevation of the atomizer, and

Fig. 2 is a front elevation thereof, partly sectional.

in these drawings a split sleeve 10 is made or such a size that by slight compression it can be inserted in the conduit leading to the manifold. hen inserted, elasticity will result in it being firmly held in position.

Springing from the inner periphery of the sleeve there is provided a standard 11 of a shape designed to give but a small resistance to the flow of gas. The upper part of this standard is enlarged at 12, such enlarge ment occupying a central position in the sleeve 10. Int-o each end of this enlargement are fixed sipndles. spindles are placed the bosses of small pro-' pellers 13 and 14:, that. have oar shaped blades.

These propellers are so arranged that under the propelling influence they will rotate in opposite directions,

On to the projecting.

To maintain the propellers on the spindles a head is fitted to each end so that each propeller has its movement in one'dlrection limited by the enlargement, and in the other direction limited by the head.

It will be an obvious modification of the invention to dispense with the split sleeve and to attach the standard directly in and to the manifold.

I claim: I v

A rotary mixing device bustion engines comprising a split sleeve for internal com-.

adapted to be accommodated in the intake I manifold, a' standard extending inwardly radially from said sleeve opposite the split thereof, said standard having an enlarged end situated axially ot' the sleeve, a headed stud car ied by said enlarged portion of the standard at each end thereo't, and a propeller mounted on each stud, said propellers being constructed to rotate in opposite directions under the influence of a current passing through the sleeve.
